Unusual Urban Bobcat Spotted in Washington, D.C. | Smart News | Smithsonian Magazine – Wow! There is more open area where I live (between Washington DC and Baltimore)…maybe there is a bobcat around here too.

Low doses of radiation used in medical imaging lead to mutations in cell cultures -- ScienceDaily - Discovery that radiation creates breaks that allow in foreign DNA must be confirmed in animal studies. Maybe this is just a pathway to learning more about how cells cope with natural amounts of DNA damage….or maybe we need to look again at the risk/benefit of some routine diagnostic testing.

Stunning Chronophotos of Powerful Osprey in Mid-Hunt – Very dramatic!

Surprising Beauty Found in Bacterial Cultures – The video is less than a minute…worth watching.

Top 25 Wild Bird Photographs of the Week: #Feeding – National Geographic Society Newsroom – They all must eat. I kept track of what they were eating in the pictures: snail, insect or other small invertebrate, frog, rodent, fish, lizard, algae, carrion, nectar, skink, or seeds.

Walnuts may be good for the gut and help promote heart health -- ScienceDaily – I like walnuts….now just to eat them more consistently!

HEADING TO THE FOREST: Bringing Joy, Accomplishment & Hope to Children | Children & Nature Network – Forest days for kindergarteners and nature kids from preschool to high school…backyard to back country. More examples of how education in nature is happening. This was part 2…the earlier article can be found here.

America's most widely consumed oil causes genetic changes in the brain: Soybean oil linked to metabolic and neurological changes in mice -- ScienceDaily – Start reading labels….there is soybean oil is in a lot of processed foods like mayonnaise and salad dressings….the list goes on and on. Evidently other soy products (edamame, soymilk, tofu, etc.) don’t cause the same changes observed with soy oil.

Blue Jay: A New Look at a Common Feeder Bird – Our feeder is not accessible to blue jays….but we see them at our birdbath frequently….and hear their calls in the forest and our yard trees.

Macro Photography Shows Stunning Details of Carnivorous Plants – Some botanical pictures to finish out the gleanings for this week.

Top 25 Wild Bird Photographs of the Week: January 2020 – Starting out with wild and wonderful birds this week.

Infographic: How does nature influence human health? – Most people intuitively know that nature has a positive impact…but now there is more and more research to quantify that impact.

The Plastics Pipeline: A Surge of New Production Is on the Way - Yale E360 – Just when I really want manufacturers to find ways to package products in something other than plastic….the industry has plans to ramp up production of plastic. Consumers can still make a difference with our purchases (or lack of purchase). I’m slowly but surely reducing the items I buy that come in plastic….always looking for alternatives.

New aqueous lithium-ion battery improves safety without sacrificing performance: Non-flammable, cost-efficient, and effective battery -- ScienceDaily – Hurray for all the battery research going on right now….hopefully there will be more and better options near term. It would certainly boost the speed we can transition away from fossil fuels.

Pylos Tomb Artifacts Suggest Trade Links - Archaeology Magazine – Amber from the Baltics, imported carnelian, pendant depicting an Egyptian goddess….the Greek site might have been a stop on a trade route.

Happy New Year from Amundsen-Scott South Pole Station – Kelly Brunt posted this on January 3rd….and I just got around to looking at it. She was one of our hosts at NASA for my HoLLIE class and then the keynote for our graduation. It was good to read about her recent activities!

Super Resilient Protein Structures Preserved a Chunk of Brain for 2,600 Years – Wow – what an amazing and surprising find! And there is has been some research to figure out how it managed to be preserved.

Towards Ecophilia: Being hopeful in spite of it all -I enjoyed the pictures and activity descriptions about children in nature.

How US sewage plants can remove medications from waste-water – Using granular activated carbon and ozonation….more than 95% of certain antidepressants and antibiotics can be removed. This is important to help reduce the development of antibiotic resistant bacteria and maybe other environmental harms as well. But it can be expensive.

The oldest person in the world turns 117 – I liked the last paragraph of the story the best: Last year, when Tanaka received her record for the world’s oldest person, she was asked about the happiest moment in her long life. Her reply was simple: “Now.” Wouldn’t it be great if we all could feel like that no matter how old we are!

Genomes Sequenced for Every US and Canada Butterfly | The Scientist Magazine® - Work by an evolutionary biologist at University of Texas Southwestern Medical Center. 845 butterfly species were studied.

Adding copper strengthens 3D-printed titanium -- ScienceDaily – Current titanium alloys used in 3D printing were prone to cracking and distortion. The copper alloy seems to overcome that problem.

When the best way to take notes is by hand - BBC Future – I like to take notes by hand….it always seemed easier to me than using a laptop (although I tried using a laptop to take notes in meetings during my career). Now it seems that it is better for internalizing concepts too. No need for me to try to change to anything else!

Blue Whales’ Hearts Can Beat Exceptionally Slowly | The Scientist Magazine® - As low as 2 times per minute! The high was 37 beats per minute.

Image of the Day: Ochre Paint | The Scientist Magazine® - Evidently ancient people heated aquatic bacteria mats growing in iron rich water to make a bright red paint which was used for rock art. The paint contains microfossils of the bacteria (Leptothrix ochracea). The red color is highly thermo-stable…something that has applicability to manufacturing.

Crows could be the smartest animal other than primates - BBC Future – Clever crows. Not so long ago we thought humans were the only ones to make and use tools.

Incredible Winners of the 2019 EPSON International PANO Awards – Panoramic photographs…a little eye candy for the week.

Trashed farmland could be a conservation treasure -- ScienceDaily – Interesting idea…but how much land is in this category and what happens to the people that are still trying to eke out an existence on that land.

Future For Silversword Plants At Halaeakalā National Park Dark – Rare plants…have not recovered as well as the Nene (Hawaiian goose) – for several reasons. Plants around the world are having to adjust to changing climate and some will not be able to change fast enough to continue to exist in the same places…some may become extinct. I hope the Silversword survives.

Top 25 Wild Bird Photographs of the Week: Seabirds – Starting with the birds this week. I’m thinking about the Delmarva birding sessions later this month…they’ll be sea birds and more to see.

Clearing damaged cells out of the body helps heal diabetics' blood vessels -- ScienceDaily – Interesting….but still a lot of research needed before it could potentialy be used in treatment.

The toxic killers in our air too small to see - BBC Future – Nanoparticles – 90% of particles by busy roads are nanoparticles below 100nm. The smaller the particles, the greater potential toxicity. Anything smaller than 30 nm can make it to through the lungs and into the blood stream (larger than that doesn’t gets past the lungs). The Global Burden of Diseases study estimates that air pollution could account for 21% of all deaths due to stroke and 24% of deaths from ischaemic heart disease.

A little prairie can rescue honey bees from famine on the farm -- ScienceDaily – Food crops can provide good food for honey bees…but maybe not for the whole season.

Agar Art Contest 2019: See this year’s winners – Art made with live bacteria.

Infrared Reveals Egyptian Mummies' Hidden Tattoos | Smart News | Smithsonian – 7 mummies – 3,000 years old. All the mummies with tattoos at the site were women.

Gabapentin: A Risky Answer to the Opioid Epidemic - The Atlantic Gabapentin has become the 10th most-commonly-prescribed medication in the US. It is viewed as a safer alternative to opioids for chronic pain….but it is problematic in combination with other sedating medication and it doesn’t work as well as hoped….particularly for back pain. It appears that looking for a quick fix for chronic pain is – again – not working as advertised.

Photography In The National Parks: My Favorite Spots For Great Photos – From Arches, Bryce Canyon, Big Bend, Acadia, and Padre Island.

Scientists Don't Know Why Freshwater Mussels Are Dying Across North America | Smart News | Smithsonian – It’s not just in one place….and may have multiple causes. But this just highlights that some mussel species that have already gone extinct…and our rivers are very different than their ‘natural’ state.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Scientists Use Agricultural Waste to Develop New Road Deicer - Yale E360 – Grape skins and other agricultural wastes rather than sodium chloride.

Poor Potato Crops Could Lead to a North American French Fry Shortage | Smart News | Smithsonian – Not a good year for potatoes in the US and Canada evidently. I wonder if prices will go up.

Hydration may affect cognitive function in some older adults -- ScienceDaily – Evidently overhydration has an impact on cognitive function as well…so it is important for older people to understand symptoms of both and actively manage their hydration.

Could Migraine Pain Relief Be Found In The Color Green? : Shots - Health News : NPR – Interesting research. Do green glasses help as much as the green LED light?

How everyday products are supercharging landfill gas, and what that means -- ScienceDaily – Some basic research that could be applied to getting more energy from our landfills.

U.S. States Have Eliminated Thousands of Environmental Protection Jobs Since 2008 - Yale E360 – “Neither EPA nor states have the funding they need to meet their responsibilities under the Clean Air Act, Clean Water Act, and other laws that protect the public’s health and our environment from dangerous pollution.” Not good.

How hacking the human heart could replace pill popping - BBC Future – Pacemakers are primitive compared to the devices that are being worked on now. The future implants will adjust to the situation…reading and writing to the nervous system to treat such things as diabetes, bladder control and chronic pain (and heart issues). Maybe they will address the root cause of some chronic diseases rather than just the symptoms.

Colouring Europe at Work: download our industrial heritage colouring book | Europeana Blog – Learn some history while your color.

IBM Changes the Energy Storage Game With Cobalt-Free Battery – Lots of research in the battery arena these days. This one caught my eye since I spent some of my career working for IBM. Maybe these will be part of the next-gen technology for batteries.

Tiny shells reveal waters off California are acidifying twice as fast as the global ocean -- ScienceDaily – Looking at shells of foraminifera in sediments provides a vertical record of ocean acidity.

Top 25 Wild Bird Photographs of the Week: Colourful Birds – National Geographic Society Newsroom – Starting off this last gleanings list of 2019 with birds! My favorite picture of this set is the scarlet macaw with a stick. Is it eating it or using it as a beak-pick?

Artistic Photographs of Mushrooms and Myxomycetes by Alison Pollack – Focusing on small things in the forest.

In Search of Australia’s Amazing Rainbow Finch – A bird survey experience…and some pictures.

Patchwork of Corn in the Snow – As of late November a lot of corn was unharvested because it was too wet. Corn needs to dry on the stalks before it is harvested and this 2019 crop may not be harvested in some areas until February or March of 2020.

Watching Wildlife on Skis – Winter wildlife….another benefit to being out and about (with proper gear) during the winter.

Life Rides the Wind in the Desert | The Scientist Magazine® - Finding life in the Atacama Desert.

Decking the halls of history: the origins of Christmas decorations – A little historical note for after the holiday.

Liver cancer deaths climb by around 50% in the last decade -- ScienceDaily – Survival rates are low too. Obesity and smoking are two preventable causes.

How Climate Change Will Affect Maryland's Birds | Audubon – I looked at the page for Maryland because that is where I live. The red-headed woodpecker is on the ‘high vulnerability’ list. The data is available for other states as well (scroll down on the ‘home’ page and select by state or zip code). The red-headed woodpecker appears on the high vulnerability list for Texas and Missouri too (those are two other states I checked).

First Global Map of Saturn's Moon Titan Reveals Secrets of Earth's 'Deranged' Twin | Smart News | Smithsonian – There are plains, sand dunes, mountains, labyrinthine valleys…and lakes of methane.

'Self-cleaning' concrete could keep buildings looking new -- ScienceDaily – Maybe a new building material…but can it be made in a ‘green’ way?

Everything You’ve Ever Wanted to Know About Turkeys – I’m just catching up on some reading…this would have been more appropriate for the Thanksgiving week gleanings…but better late that never. Turkeys are interesting birds!

Air Pollution Tied to Brain Cancer: Study | The Scientist Magazine® - Combustion-related nanoparticles can reach our brain! The concentrations of these particles in highly polluted areas are also causing other health related problems as well. For example, the air pollution in Kabul, Afghanistan may be causing more deaths than war in that area

Owling: A Field Guide to Finding Winter Owls – Seen any owls? They are often easier to hear than see.

Slideshow: Images from The World Beneath | The Scientist Magazine® - A few pictures from a new book about sea creatures and coral reefs. Lots of vibrant color and camouflage.

Eating in sync with biological clock could replace problematic diabetes treatment: An early-morning, carb-filled meal improves glycemic control among diabetics -- ScienceDaily – We are shifting our meals…largest one at midday…smallest one at night. If we eat a high carb meal it will be at breakfast. I had gingerbread cake this morning!

Sunlight-Tracking Polymer, Inspired by Sunflowers, Could Maximize Solar Power | Smart News | Smithsonian – Another way that solar panels can gain efficiency.

Springfield Plateau: Yellowjacket Nest – A yellowjacket tale from Springfield MO. I was surprised that ice was the treatment for a sting. I’ve always used baking soda with ice as the backup plan if there isn’t any baking soda available.

Why biodegradables won’t solve the plastic crisis - BBC Future – There are only pieces of a solution at this point….nothing comprehensive. It seems like the best strategy for at home is to reduce all single use plastic as much as possible. There are some easy things like reusable shopping and produce bags, but it becomes hard quickly. So many groceries and toiletries only come in plastic containers.

Remote Sensing Data Advances Soil Health Science – Cover crops and no-till practices were an advantage in record-breaking rainfalls of spring 2019.

How the House Finch Conquered Your Feeder…and A Continent – A little history of House Finches – originally from the southwest and Mexico…now in found widely across North America.

How the Aztecs could improve modern urban farming: Chinampas: An old technique might provide new solutions to sustainable urban agriculture -- ScienceDaily – The article made the multiple harvests per season seem feasible in tropical wetlands…not so much in the temperate zone where the artificial islands would go through a real winter although maybe it would just mean the use of cover crops during that time period.

Top 25 Wild Bird Photographs of the Week: December – Bird photography to enjoy!

Listening to Nature: The Emerging Field of Bioacoustics - Yale E360 – An up and coming technology for remote sensing of birds, insects, frogs and other animals.

Red Tides Under the Microscope | The Scientist Magazine® - It’s surprising what we don’t yet know about the organism responsible for red tides – Karenia Brevis. Spanish explorers of Florida in the 15th and 16th centuries described fish kills in Gulf waters. The first official documentation was in 1882 – published in the Proceedings of the US National Museum. This article is about what we know….and where more research is needed.

The woman who reshaped maths - BBC Future – Hilda Geiringer…a refugee from the Nazis. A BBC Future column celebrating a ‘missed genius’ whose contributions are still notable in the world today.

NOAA weather balloons find no zero-ozone regions above South Pole during 2019 ozone hole season | NOAA Climate.gov – A little science…a little history…a projection. The positive message – if the trend continues, it’s estimated that the ozone layer will recover around 2070.

Abrupt shifts in Arctic climate projected: Likelihood of an abrupt increase in wildfires also noted -- ScienceDaily – With specific modeling of permafrost as it continues to degrade….it appears that the changes won’t be as gradual as  previously assumed.

Lake On Bottom Of Halema‘uma‘u Crater At Hawai'i Volcanoes National Park Now Bigger Than Football Field – The lake was noticed back in July….and is being studied with instruments on drones. More information is at the National Park Service site for the park.

Top 25 Wild Bird Photographs of the Week: Wild Birds – National Geographic Society Newsroom – I always enjoy the bird photography compiled by National Geographic every week.

Offshore Wind Has the Potential to Fulfill Global Electricity Demand 18 Times Over - Yale E360 – Hurray for this potential….the transition is the challenge.

AP: At least 1,680 dams across the US pose potential risk – There is a link to an interactive map that shows where the 1,680 dams are located. The last paragraphs of the article are the most troubling. There are a lot of dams with unknown status. Roughly 45% of Texas dams are exempt from regulation…in Missouri safety inspections are only done on 650 of its more than 5,000 dams. And states that know about problematic private dams often can’t identify the owners to address the dam’s issues.

Aging in good health: The inequalities are widening -- ScienceDaily – A study with over 11 million people tracked for 25 years!

Susquehanna Sediment in the Chesapeake Bay – Imagery of big rivers and the Chesapeake Bay after a storm at the end of October…. close to where I live. On a positive note - the sediment (even after the record rains earlier this year) has not damaged the underwater grasses on the Susquehanna Flats as much as was initially feared.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

US-born residents more than 5 times likely to use prescription opioids than new immigrants -- ScienceDaily – Evidently new immigrants are often healthier than non-immigrants despite their poorer background….which is a clue that there is something about American culture that influences opioid use.

Top 25 Wild Bird Photographs of the Week: Spectacular – National Geographic Society Newsroom – Enjoy the birds! We are enjoying the birds coming to our feeder and (heated) bird bath…in the trees around our house. They are easier to see now that the leaves have fallen from the tees.

50 Fish, 50 States: Small Stream Wonders – Cool Green Science – Lots of small fish! When we are in the streams with high school students, we often find small fish but since they aren’t what we are looking for – we simply put them back without identification. Maybe I should look for a simple small fish ID to take a long and start to photograph them too.

A Giant Treehouse 'Like A Castle' Is Destroyed By Fire In Tennessee: NPR – My sister and I visited this giant treehouse in 2012 when we were in that area of Tennessee. Sad that it’s gone.

Hurricanes have become bigger and more destructive for USA -- ScienceDaily – An expensive trend.

When Turkeys Attack – I’m glad the wild turkey population is recovering….hope we can develop strategies to co-exist!

Scientists study impact of sediments and nutrients from Conowingo Dam on Chesapeake Bay -- ScienceDaily – Close to home. The base of Conowingo Dam is where we go to view Bald Eagles. There is a lot of concern now about the sediment build up in the reservoir --- state governments and the utility are working to determine best options for prolonging the energy generation capacity of the dam and improving water quality into the bay.

Big Box Stores Leading the Shift to Renewable Energy - News | Planetizen – Wal-Mart and Target are all in….what about other big box stores? What about owners of shopping centers? Lots of stores are in leased spaces.

Five Architectural Firms Retained to Redesign National Mall Tidal Basin – Another ‘close to home’ in this set of gleanings. This one is in the District of Columbia. Think of the Jefferson Memorial and the cherry blossoms. Flooding has increased over the time we have living in this area (now over 35 years). Hope they can develop a good design and get the funding to implement it.

Manta Ray Populations Have Complex Social Structures | The Scientist Magazine® - A study of the reef mantas as they aggregate around the reefs of the eastern Indonesian archipelago Raja Ampat. The study showed two distinct groupings: one dominated by older females and the other a mix of sexes and ages.

We asked women around the world these 6 provocative questions – Thought provoking and a good read for the answers from women.

Computer science classes break down cultural barriers, study shows -- ScienceDaily – This was certainly true for computer science classes and gender barriers in the US during the 70s and early 80s….and then it wasn’t. Hopefully the same does not happen in the future to this project and projects like them.

Renaissance Nun's 'Last Supper' Painting Makes Public Debut After 450 Years in Hiding | Smart News | Smithsonian – A little art history -- Plautilla Nelli. The article includes pictures before and after restoration of the painting.

Happier Babies Have an Edge - Scientific American Blog Network – The more children experience happy emotions, the more time they spend building skills and relationships that help them in the future.

900 Pythons Removed from South Florida – That’s a lot of snakes. Kudos to the Python Action Team. There are other organizations (government and non-profits) working on this too. I wish the article would have included information about what they do with the snakes after they are captured. Presumable they are killed.

Study: 95 percent of baby food contains traces of toxic metals - UPI.com – Not good. The full report referred to in the article is available here. I wonder if pediatricians are changing their recommendation when it comes to some foods (like rice cereal for babies).

Newly discovered virus infects bald eagles across America -- ScienceDaily – Over 1/3 of America’s Bald Eagles are infected…and it might be causing a fatal disease – Wisconsin River Eagle Syndrome.

Eavesdropping on Soil Insects Could Aid Pest Management – Earlier this week I was hiking with second graders…soil auger in hand. There was big excitement when one of our samples include a beetle grub! And then this article appeared a few days later. The grub moved a bit and I wonder if it was one that made stridulations (chirps); if so – they weren’t loud enough for us to hear.

A Field Guide to Elk Bugling – Cool Green Science – Elk are not just in the western US. They have been reintroduced into the east.

Top 25 Wild Bird Photographs of the Week: Birds in Flight – National Geographic Society Newsroom – Some familiar birds in this group – norther shoveler, northern pintail, red tailed hawk…some others.

Could Brain Activity During Sleep Be a Biomarker for Alzheimer's? | The Scientist Magazine® - The study only included 31 individuals…so replication with larger samples is still needed. We do need a non-invasive and early way to diagnosis Alzheimer’s.

Edge of the Ice – Brown bands at the edge of the ice are layers of ice deposited at different climate periods. Usually we only see the layers in ice cores.

Better way to teach physics to university students -- ScienceDaily – Kudos to the physicists and educators at University of Kansas. Hopefully other universities and maybe high schools can benefit from these ideas.

Climate Change Threatens Hundreds of North American Bird Species: “It’s a Bird Emergency” - Yale E360 – This on top of the declines we’ve already seen in insects and birds that feed on them. The ‘bird emergency’ is not a future event…it is already happening.

New test diagnoses Lyme disease within 15 minutes -- ScienceDaily – It would be great to have a faster test for Lyme disease. Most people are probably not tested until they have symptoms…and that’s sometimes too late to avoid permanent damage.

The peculiar bathroom habits of Westerners - BBC Future – A little cultural dissonance…that we don’t often hear about.

Humans have salamander-like ability to regrow cartilage in joints: The process could be harnessed as a treatment for osteoarthritis -- ScienceDaily – Wow! If works, there will be a lot fewer joint replacements as people get older….and moving would a lot less painful.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Scientists Find Way to Fully Recycle Plastics Without Losing Quality - Yale E360 – I hope this process undercuts plastic manufacturing from fossil fuels…plastics should not be the glide path for the oil companies! The heating of the plastic to 850 degrees for this process should be done with renewable energy. And what happens to the parts that don’t get recycled (I assume there is waste from the things that weren’t plastic that got into the stream (i.e. ‘dirty’ containers).

Top 25 Wild Bird Photographs of the Week: Bird Interactions – National Geographic Society Newsroom – Birds with other birds (not always the same species).

Maya Tomb of the Unknown Red Queen - Red from cinnabar (mercuric sulfide) power that covered everything inside the limestone sarcophagus…a mask of malachite.

Time Spent in Nature Is Good for You | The Scientist Magazine® - Spending at least 2 hours in nature per week is strongly correlated with self-reports of being in good health and having high well-being…..based on a study in the UK with 20,000 participants between 2014 and 2016. Intuitively – the idea seems right. But what does ‘time spent in nature’ really mean and what is it that causes the correlation? Do you have to be outdoors or is viewing it enough? I am outdoors in beautiful natural places (gardens, forests, seashores, rivers and lakes) so frequently…the 2 hours per week is at the low end for me…except for the coldest or wettest weeks.

Cooking food alters the microbiome: Raw vs. cooked diets have distinct effects on both mouse and human gut microbes -- ScienceDaily – No recommendations from this research but lots of prompts for further research.

The Short List Of Climate Actions That Will Work | CleanTechnica – These are country or continent type actions like: electrify everything, overbuild renewable generation, build continent-scale electrical grids and marks, fix concrete, change agricultural practices, shut down coal and gas generation aggressively. Some of them can be impacted by individual decisions…to move in the direction. For example – 1) The CSA I belong is on a path to not use plastic to control weeds and retain moisture around their crops. 2) The next house I buy (in the next 2-3 years) will be all electric and have solar panels…maybe battery storage too….maybe geothermal heating/cooling. 3) The next car I buy will be an EV rather than a plug-in hybrid like I have now. And I can change my yard into a mini-forest (of redbuds, dogwoods, spice bush, hollies….not huge trees but ones that are native to the area where I live).

Air Pollution May Damage People's Brains | The Scientist Magazine® - Mortality, respiratory health, cognition, and social behavior. This is scary. This is yet another reason to move away from fossil fuels.

Humankind did not live with a high-carbon dioxide atmosphere until 1965 -- ScienceDaily – I was in 5th grade in 1965. It was the grade between two memorable events: seeing a tornado just before it touched the ground and traveling with my parents to Mexico City for a weeklong vacation (two firsts: on an airplane…and out of the US). But the cross over to a high-carbon dioxide atmosphere has the greater long-term impact. I already suspect that unless something changes dramatically, climate change by midcentury will probably shorten my life.

Ailing U.S. pecan industry calls on India to reduce tariffs - UPI.com – I couldn’t find an update on this story from a few weeks ago. Evidently China used to buy 40% of the pecan crop in the US but now there is a tariff and the market is gone. So, the farmers are trying to develop the Indian market. It’s been tough to be a farmer for many years…but the tariffs have added even greater challenges.

Stressed out: Americans making themselves sick over politics: One in five report lost sleep, damaged friendships -- ScienceDaily – If individuals are stressed by politics….hopefully they’ll realize that it’s time to implement strategies to reduce the stress. Spending less time on ‘news’ would provide time to shift focus to other aspects of life – skew toward activities that make you happy and help others too. ‘Staying informed’ of politics 24/7 should not be a priority (although participating in elections should be).

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

New report deepens understanding of wind-wildlife interactions -- ScienceDaily – This article overviews the report. The 24 page report is available here. The amount of collaboration between the industry, government, conservation, academic and scientific organizations is significant and ongoing.

Marsh-Billings-Rockefeller National Historical Park Celebrates Forests – Maybe I’ll go to Vermont for this festival next September – if it’s an annual event.

These surreal jarred fish tell an urgent story of extinction – The Royal D. Suttkus Fish Collection – nearly 8 million preserved fish…a window into how 20th century development changed the Southeastern US fish….a record of that destruction.

No bones about it, this protein slows down fracture-healing -- ScienceDaily - Abundance of ApoE may explain why older people have trouble healing broken bones. Turning off ApoE completely causes fat to be deposited in arteries (a cardiovascular problem) so treatment options may involve lowering ApoE for short periods of time.

O Canada! We Like Your Food Guide – Food guides from Canada (and some other countries) … some differences from the US. Canada merges ‘dairy’ in with protein foods rather than featuring it as an independent group.

Scientists Are Getting Better at Predicting Hurricane Intensity – A new algorithm has been developed to include the complicated physical mechanisms of tropical cyclone dynamics and the way they interact with upper-ocean and atmospheric circulation. It may reduce the error of tropical cyclone prediction within a 24-hour period by 16%. Every little bit of improvement in prediction means better preparations when an intense storm is approaching.

Artworks of the Dark Zone – From caves in Tennessee and Alabama. Artwork incised in mud and inscriptions. A slideshow.

How Penn State is Cutting Greenhouse Emissions in Half – and Saving Money – Kudos to Penn State. I wonder how many other universities are doing similar things.

Empty Meditative Landscapes Visualize the Tranquil Beauty of Silence – A visual treat

Ed Hawkins “Climate Stripes” May be the Most Important Science Image so Far in This Century – Effective visualization of lots of data…becomes information. The next step is action.

Climate change may cut soil's ability to absorb water -- ScienceDaily – Climate change impacts everything. The models only model pieces of the puzzle. This study was looking specifically at water and soil – not currently included in models..

The Iguana Invasion – Cool Green Science – They’re a common sight in Florida….and the state is now advising people to kill them. No talk of eating them like they do in their native range further south and the Caribbean where they are farmed.

Sigiriya, the 'Lion Fortress' of Sri Lanka – A Heritage Site that survived by being hidden by forests…and being remote enough to not be marred by modern weapons of war.

Impostor syndrome is more common than you think -- ScienceDaily – Seeking social support outside academic (or workplace) specialization seems to be the best coping strategy.

Pregnant Moms' Air Pollution Exposure May Affect Babies' Health | The Scientist Magazine® - Research is ongoing. The first correlation was between air pollution and low birthweight/preterm birth. Current research is on other health consequences in the early life of the baby and beyond…looking beyond correlation to the underlying mechanism.

Top 25 Wild Bird Photographs of the Week: October – The headline picture is of a Green Heron!

BBC - Future - The simple words that save lives – Communication in an emergency…if it goes wrong…tragedy.

Despite growing burden of diet-related disease, medical education does not equip students to provide high quality nutritional care to patients -- ScienceDaily - Researchers call for improved nutrition education to be integrated into the medical curriculum. This makes sense to me…but why hasn’t it been done long before now?

Iceland's Seabird Colonies Are Vanishing, With "Massive" Chick Deaths – Kittiwakes, puffins, murres, fulmars – Chicks die…nests with eggs abandoned. Total breeding failure for many of the birds. For the Puffins it has been happening since 2005. Lots of changes caused by climate change funneling pollution from the North America and Europe to the North Atlantic: mercury ubiquitous and rising fast in some areas, brominated flame retardant, pesticides, PCBs, chemical laced microplastics. A caption under one of the pictures: “In Iceland, levels of PCBs and other contaminants are so high in murre eggs that people shouldn’t eat them.”

BBC - Future - The desert soil that could save lives – Bioprospecting for antibiotics and industrial biocatalysts from bacteria that survive in extreme environments like the Atacama or Antarctica

Top 25 Wild Bird Photographs of the Week: Resident Birds – National Geographic Society Newsroom – ‘Resident’ around the world….beautiful birds.

Global warming may threaten availability of essential brain-building fatty acid -- ScienceDaily – Impacts of climate change go far beyond the climate models…many probably still to be discovered.

Recovery: Restoring the Floodplain Forest – Cool Green Science – I started reading the article since I am always interested in how restoration projects are created and evolve…but the aspect I’ll remember about it was the info about a tree: American Elms. Ones resistant to Dutch Elm Disease are among the trees being planted as part of the restoration. I grew up at a time when the elms were all dying. There were several I remember at my grandparents’ house in Oklahoma and a tree beside the playhouse at the house we moved to in Dallas in the early 1970s. It was already sickly. I wonder if there will soon be enough varieties and availability of elm trees for them to become landscaping trees again.

Interview: Self-Taught Myanmar Photographer Captures People Working – Capturing images of human-made place. Now I am wondering what I would photograph in my part of the world to do something equivalent.

Crying over plant-based milk: neither science nor history favors a dairy monopoly – An article about milk….and the argument about what the word means. The dairy industry wants it to mean milk from cows…but milk has been used more broadly to mean white liquid for a very long time. We even have plants with ‘milk’ in their name (i.e. milkweed)!

Pictures of India's UNESCO World Heritage sites – Rich cultural and natural history…reflected in places selected to protect.

'Report card' on diet trends: Low-quality carbs account for 42 percent of a day's calories: Older people, those with lower income, and those with less education face greater hurdles -- ScienceDaily – With results like this, maybe we should come up with better ways of helping people learn about nutrition. Do our schools help students learn about nutrition? How many adults have logged their food intake into an app and discovered how good (or poor) their food choices are? The current outreach strategies relative to nutrition are not enough. Sometimes even doctors seem to lack any expertise other than knowing that a patient is overweight/obese or their waist is too large.

Create Wildlife Habitat Around Your House – Cool Green Science – I already have a bird bath and feeder, milkweed patch, brush pile and some native trees (maple, sycamore, tulip poplar, oak). Even a spongy compost pile is habitat (this summer I had puddling tiger swallowtails on it)!

Komodo Dragons Have Skin That Looks Like Chain Mail | Smart News | Smithsonian – Four distinct morphologies of osteoderms in the skin of adult Komodo dragons. Another example of the wonderful complexity in the natural world.

Marriott Aims For 33% Reduction in Plastic Waste | CleanTechnica – Marriott will do this by 2020. They will do away with the tiny tubes of shampoo, conditioned and other toiletries, replacing then with larger bottles affixed to the walls. It’s a step in the right direction and we all need to be looking for these steps that are ‘easy.’ We also need vendors to do their part and transition away from plastic packaging. Remember that plastic is relatively recent; there are still people alive that remember a time without it! But we need new solutions rather than just going back to pre-plastic days….it will take focus and creativity…and a demand from all of us – to rid ourselves of the negative aspects of plastic.

Top 25 Wild Bird Photographs of the Week: Endemic Birds – National Geographic Society Newsroom – Beautiful birds.

Dam Removal Complete on Maryland's Patapasco River - News | Planetizen – Some close-to-home news. I had been tracking these dam removals over the past few years and hearing reports about preparation and results at the annual Maryland Water Monitoring Council conference.

Harmful Algal Blooms (Red Tide) – Information and maps about algal blooms. I looked at the Chesapeake Bay part of the site.

Ghost Crabs Use Teeth in Their Stomachs to Ward Off Predators | Smart News | Smithsonian – This article reminded me of the ghost crab we saw on Two Mile Beach near Cape May, New Jersey last May. We must have been far enough away to not be too threatening; the crab did not make any noise at all.

Drinking tea improves brain health, study suggests -- ScienceDaily – I like to drink tea…and it gets even better with studies like this. The opposite it true for soft drinks…even the diet ones. Those I need to reduce or stop drinking completely.

Can We Turn Down the Temperature on Urban Heat Islands? - Yale E360 – Work to gather more detailed information about the heat islands within cities. The extra details help clarify strategies of how to reduce them. Some of the ideas I had heard before…others – like varying building heights – I had not.

Topography could save sensitive saguaros as climate changes -- ScienceDaily – We haven’t been back to Tucson since my daughter finished her graduate work at University of Arizona; but I always browse articles about the place. This research was done at U of A…and I was glad that the iconic saguaros might adapt to climate change – at least on Tumamoc Hill.

A Field Guide to The Feral Parrots of the US – Cool Green Science – Wow – there are a lot more of them than I realized.

Neurotoxin lead sometimes added to turmeric for brighter color -- ScienceDaily – Very scary. Are we sure they don’t export the tainted turmeric?

These Caterpillars Can Detect Color Using Their Skin, Not Their Eyes | Smart News | Smithsonian – A little surprise…but insects probably have a lot of adaptations developed over eons that are challenging to imagine.

Five weird and wonderful ways nature is being harnessed to build a sustainable fashion industry – New dyes from enzymes, ‘leather’ from mushrooms, lacy fabric made from plant roots that grew that way (watch the video), cellulose for fabrics derived from manure!

Aesthetics of skin cancer therapy may vary by treatment type -- ScienceDaily – Hopefully these findings will guide doctors to use the more aesthetic treatments…since they all have about the same recurrence rates a year after treatment.

On the Alabama Coast, the Unluckiest Island in America - Yale E360 – Dauphin Island…when does everyone decide that these places can’t be saved…should not be rebuilt. It’s not something we are dealing with very well as individuals or as a nation.

Deer browsing is not stopping the densification of Eastern US forests -- ScienceDaily – Deer hurt the understory but the canopy is more impacted by the greater density of the big forest trees (because of fire suppression) and that red maples are growing in areas where young oaks, hickories, or pines would have grown previously. But wouldn’t the deer browse young trees? In our area – the forests have also changed quite a lot in the last 20 years with the decline of the hemlocks and now the ashes. This study – done in Pennsylvania – did not comment about those issues.

Top 25 Wild Bird Photographs of the Week: September – These photographs are always worth a look….birds are so beautiful.

North America has lost 3 billion birds – And fresh from looking at the wonder pictures of birds….this sobering news: North America has lost 25% of its bird population and it’s all happened in the last 50 years. More than 90% of the loss is in just a dozen bird families that includes the sparrows, warblers, blackbirds, and finches. Grassland birds have suffered a 53% loss. Potential causes: habitat degradation, urbanization, and the use of toxic pesticides.

Staying at elementary school for longer associated with higher student attainment – My daughter didn’t seem to have a problem transferring from elementary to middle school after 5th grade…but the middle school was next door to the elementary school, and she was doing well in school. The results of this research will have to overcome the school building infrastructure in many areas. Change happens slowly with school systems. So far I haven’t seen a change in start times for high schools even though there are studies that say that early starts are not good for high school students (in our area, they have always started before the elementary and middle schools).

Spotted in Kenya: a baby zebra with polka dots – I hope there is a follow up story on this baby. Will the pattern make it more susceptible to fly bites? Another note from the article: Zebras are accepting of difference…animals with atypical coat patterns fit right into the herd.

Drought Reveals Lost “Spanish Stonehenge” – The Dolmen at Guadalperal has resurfaced from the Valdecanas Reservoir in western Spain due to lower lake levels from dry, hot conditions this year. It has been submerged for 50 years. Hopefully someone will make a good 3D tour of the place.
